Set your Voltmeter to its lowest setting and hold the probes at arms legth apart and move them together and you will see a reading that changes depending on the distance apart. Do it under flourescent lights and it will be a larger voltage. Do it near motors or transformers for a test.
I did that, and got about 0.15mV, I think. I get larger voltages (>200mV) when touching the probes. I used an Arduino EMF Detector, and was able to measure EMFs as voltage near AC appliances.
